My period came a week early and meant that I was on during my holiday!! My period tends to be really heavy and I frequently have accidents: stains on clothing and seats. This means I often wear heavy, dark clothing when I'm on. You can imagine my horror when I came on during my hols in a hot country. Luckily, I bought these along. I wore my normal panties and a pad and then these briefs over them. I didn't always have regular access to toilets, my clothing was thinking and brightly covered and i was not able to change as frequently as I would like to. However, these panties prevented any embarrassing leakage from seeping into my clothing or onto seating. I did actually leak into the pants but the protective layer stop any leakage. I just wish they were more affordable to have more of them as they are needed day and night when I'm on. A must buy for anyone with heavy periods. recommend Funnry"

"I tried these out for the first time yesterday and was impressed. The first day of my period is super heavy and these lasted all-day, 16 hours total,without leaking or even making me feel anxious they would leak. They were super comfortable too and didn't show panty lines since they're shorts. Iwas worried they'd be sweaty or damp feeling, but the fabric is breathable and the absorbent layer very quickly pulls in moisture so you don't feel likeyou're sitting on a wet pad constantly. They were also easy to rinse out in the sink at the end of the day and I don't feel weird at all about tossing them inwith my regular laundry. I'm ordering another two-pack."

"DUE TO endometriosis and PCOS) and I am in a larger size range than other places cater toward. I love this product. They arecomfortable to wear and have held up to repeated wash/dry cycles. One of my problems with other brands (other than them not offering a good plus sizerange) is that the waterproof area that prevents leakage doesn't extend up in the hind end....." "These underwear have waterproof coverage all the wayup to the waist in the back. It feels a little funny if I have to fart, like the underwear balloons out because waterproof = not breathable but it has

protected my pants. And like I've been saying to people, it's a good period if I don't ruin my clothes to overflow or leakage...
